High-precision integrated ball screw incorporated into a stepper motor for continuous high-positioning linear motion.
Available with or without guide, adjustment knob or electromagnetic brake. Reduces the number of components such as couplings and secondary external guides to make equipment more compact, quicker to install with less parts to order.
Built-in Controller (Stored Data) allows for easy networking and simplified multi-axis control.
Standard (0.72°) or High-Resolution (0.36°) Motor Types
Built-in Controller (Network Type) or Pulse Input Type Drivers
24 VDC Input
Repetitive Positioning Accuracy
Ground Ball Screw = ±0.003 mm
Rolled Ball Screw = ±0.01 mm
The DRLII Series features a structure in which the rotor is hollowed out and the ball screw is stored inside. The rotation of the hollow rotor rotates the ball screw nut and by setting up an anti-spin mechanism* on the tip of the ball screw, the ball screw shaft is moved in a linear manner.
Because the ball screw shaft is stored in the hollow rotor section, the maximum stroke is secured with the shortest overall length. Also, a large bore bearing is positioned on the outer circumference of the ball screw nut in order to directly receive the large thrust loads generated in linear motion.
*Not necessary for the guide type.
High Positioning Accuracy
The ball screw nut is linked with the hollow rotor. Through the coupling rigidity and other aspects of parts combination, the impact of backlash has been minimized achieving high-precision positioning.
